SUPPORT FOR SIZED-LADDERS. 7

To all whomz't may concern Be it known that I, HOWELL C. BROWN, a citizen of the United States, residing at Morning Sun, in the county of Louisa and State of Iowa, have invented certain new and useful Improvements in Supports for Silo-Ladders, of which the following is a specification, reference being had to the accompanying drawings;

My invention relates to silos and particularly to means for supporting ladders in conjunction with the wall of a silo.

The primary object of my invention is the provision of means whereby the ladder may be hung from a support mounted upon the silo, this support being so constructed as to lock the silo ladder in position and prevent any chance of accidental detachment.

A further object of the invention is to so construct the supporting means that the ladder may be applied to any portion of the silo, the support being so constructed that when weight is placedu'pon the ladder,

the support will swing inward toward the wall of the silo, thus binding the ladder against the wall of the silo and preventing its detachment from the wall or support.

Other objects will appear in the course of the following description.

In the accompanying drawing forming a part of this application, Figurel is a side elevation of a portion of a silo with my ladder holding attachment applied thereto, the ring 7 not being swung to its ladder supporting position under the weight of the ladder; Fig. 2 is a like View to Fig. l, but viewed in a plane at right angles thereto and showing the weight of the ladder causing a depression of the hoop 7, and therefore the swinging of the hoop downward to cause the ladder to bear against the face of the silo; Fig. 3 is a detail sectional view showing the manner in which the hooks on the ladder engage with the hoop 7; Fig. 4 is a detail sectional view showing the manner of supporting the hoop 7 upon the hoop 3 Referring to these drawings, 2 designates a silo of any ordinary or usual construction and provided with the usual hoops 3. The uppermost hoop 3 is illustrated as the means for supporting the ladder support. To this end, a plurality of hangers 4: are loosely mounted upon the uppermost hoop 3" and depend downwardly and outwardly therefrom. These hangers are shown as formed each with an elongated eye 5 at its 6 at its lower or outer end. Supported in the eyes ,6 'of all of the hangers, is a hoop Specification of Letters Patent.

inner or upper end and an elongated eye 7 which is normally spaced from the wall of the silo. A ladder 8 of any ordinary or usual construction is provided which is formed upon its legs, adjacent its upper ends, with the outwardly projecting hooks 9 which are adapted to, engage over the" hoop 7.

From the construction heretofore described, it isobvious that the ladder can be disposed with its upper end between the outer hoop 7 and the hoop 3 and with its hooks engaged over the outer hoop and that as soon as the weight ofaman is placed on the ladder, the hoop 7 will swing inward against the ladder or toward the wall of the silo, thus pressing the ladder against the inner hoops and the silo wall and locking the ladder absolutely securely.- It will, of course, be obvious that the ladder may be moved entirely around the siloby shifting it along the hoop 7. and lowering it when the ladder is passing the supports that suspend the outer hoop.

' While I have described the hoop 7 as suspended from the hoop 3 of the silo, yet I do not wish to be limited to this construction as this hoop,7 might be suspended in the manner described from the top of'the 1 silo, from the sides thereof, or in any suitable manner. The supportlng members l may be of. any number required and I do not wish to be limited to any specific length for these supports, nor toany specific form therefor. My invention is simple, entirely practical and provides means whereby a ladder may be readily placed or hung from the walls of a silo so that the several hoops thereof may be tightened. It is obvious that when tightening these hoops, it is necessarythat the ladder shall be, disposed against the wall of the silo and that the ladder cannot be inclined against the wall,

without making it difficult to tighten the hoops.

It is, of course, obvious that I do not wish to be limited to any speclfic form of ladder nor specific form of hooks therefor. 7 Having thus described this invention, what I claim is 2- .1. The combination with a structure, of a hoop entirely surrounding and normally.

equally spaced at all points from the structure but movable into eccentric relation thereto upon the application of 'weight'to one portion of the hoop, and a ladder coacting with the hoop and having sliding detachable engagement therewith.

2. The combination with a structure, of a hoop entirely surrounding and normally equally spaced at all points from the structure but movable into eccentric relation thereto upon the application o1 weight to one portion of the hoop, and a ladder coacting with the hoop and having sliding cletachable engagement therewith, said ladder being disposed 1 with its upper end between the hoop and the wall of the structure whereby the depression of one portion of the hoop underJthe weight of :the ladder will cause the hoop" to swing into eccentric position and :clamp the ladder between the hoop and the structure.

3. The combination with a structure and a hoop having a greater diameter than the structure extending therearound and suspended therefrom formovement into eccentric relation to the structure, of a ladder 'slidably and detachably engaging the hoop having outwardly projecting hooks engaging the hoop, the ladder being disposed between the hoop and the wall of the structure whereby on the application of weight to the ladder that portion of the hoop-engaged by the ladder will swing in- -ward toward the structure and clamp the ladder toward the structure.

4. The combination with a structure and a hoop extending around the structure and disposed against the wall thereof, of a hoop greater indiameter than the first named hoop and entirely surrounding'the wall of the structure, hangers pivotally' connected. to the first and second namedhoops and normally extending outward and downward from said structure to support the second named hoop in uniformly spaced relation from the wall of the structure, and a ladder having its upper end provided with outwardly projecting hooks engaging over said second named hoop and'disposed between the second named hoop and the wall of the structure.

5. The'combination witha silo, of a hoop entirelysurrounding the upper end of the silo but normally spaced therefrom, hangers pivota'lly'mounted upon the silo wall normally extending downward and outward.

therefrom and flexibly connected tosaid hoop at a plurality of points wherebythe hoop shall be normally supported in uni tormly spaced relation to the silo wall "but hoop, and a ladder having outwardly pro- ]ectmg hooks engaging the hoop and shiftable therealong whereby when; the ladder 1s inward toward T may swing inward at one point whenweight 1s applied to that portion. of the.

engaged with the hoop the hoop will swing the silo :and the ladder willbeclamped between said hoop and the silo i wall.

6. The combination with the cross sectional diameter oi the hoop,

said hoop being therebyflexibly suspended from the structure so that it will normally be uniformly spaced therefroni but may swing inward toward the wall of the structure when weight is applied to one portion of. the hoop, anda ladder adapted to engage with the hoop to causethe hoop to swing inwardand carry the ladder against the wall of the structure.

7. The combination with ported thereon, said'links normally extending. outward and downward, each of said links havingan elongated eye at its lower end and a' hoop entirely surrounding the building and uniformly. spaced therefrom,

said hoop passing loosely through theeyes of said links and being slidable there a structureyor" a hoop entirely surrounding the structure, links pivotally connected to the wall of the I structure, each link at its lower end having an elongated eye through which said hoop -looselypasses,'the eye being longer than a building, ot a plurality of links disposed. at intervals around said building and pivotally sup-- through and movable therein, and a ladder.

slidable along the hoop and engageable therewith at various -'pO1I1l3S whereby the weight of the ladder will cause that portion YHOWELL C. BROWN: l Vitnesses W. R. STERETT, PIAZEL 0. MCCLURKIN.
